Chiral magnetic textures give rise to unconventional magnetotransport phenomena such as the topological Hall effect and nonreciprocal electronic transport. While the correspondence between topology or symmetry of chiral magnetic structures and such transport phenomena has been well established, a microscopic understanding based on the spin-dependent band structure in momentum space remains elusive. Here, we demonstrate how a chiral magnetic superstructure introduces an asymmetry in the electronic band structure and triggers a nonreciprocal electronic transport in a centrosymmetric helimagnet α-EuP.

Hydrogen is a zero-emissive fuel and has immense potential to replace carbon-emitting fuels in the future. The development of efficient H sensors is essential for preventing hazardous situations and facilitating the widespread usage of hydrogen. Chemiresistors are popular gas sensors owing to their attractive properties such as fast response, miniaturization, simple integration with electronics and low cost.

Background: Earlier studies have documented the risk for sinoatrial node injury and phrenic nerve paralysis as complications following radiofrequency catheter ablation for electrical isolation of the superior vena cava (SVCI).
Objectives: The aim of this study was to assess the safety and feasibility of SVCI in patients with atrial fibrillation undergoing pulsed field ablation (PFA) METHODS: Six hundred sixteen consecutive patients undergoing PFA for pulmonary vein isolation plus SVCI were included in this multicenter analysis. Superior vena cava (SVC) ablation was performed under the continuous guidance of intracardiac echocardiography.

Increasing the degree of freedom for quantum entanglement within tensor networks can enhance the depiction of the essence in many-body systems. However, this enhancement comes with a significant increase in computational complexity and critical slowing down, which drastically increases time consumption. This work converts a quantum tensor network algorithm into a classical circuit on the Field Programmable Gate Arrays (FPGAs) and arranges the computing unit with a dense parallel design, efficiently optimizing the time consumption.
